T0 (LZ/Z whom, it muy concern.'

Be it known that I, FRED P. PURDY, a citizen of the United States,residing' at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inJar-Covers, of which the following is a specification, reference being'had therein to the accompanying drawings.

This invention relates to improvements in jar-covers; and the object ofmy invention is to produce a hinged cover which may be easily attachedto jars for holding pickles and similar articles and constructed in amanner to effect an air-tight closure when the cover has been closeddown and to so construct the cover and attaching-rim that the formerwhen closed will be automatically locked against casual or accidentalopening bythe suction formed by the cover resting upon the rubberattached to the metallic rim, which is a part of the frame of thejar-cover, but will be capable of being readily lifted when it isdesired to gain access to the contents of the jar, this jarcover beingparticularlyT adapted for pickle-jars to prevent flies and other bugsfrom entering into the pickle liquid vand a cover which will notaccidently become detached from the jar.

The invention consists in the combination of elements and in certainparts of construction entailed in the combination of said elements toobtain the desired result.

A full understanding .of the invention can best be given by a detaileddescription of a preferred construction embodying the various featuresof the invention, and such a description will now be given in connectionwith the accompanyingdrawings, and attain my object by the mechanismthere illustrated, showing such preferred construction, and the featuresforming the invention will then be specifically pointed out in theclaims.

In said drawings, Figure l isa plan view of the cover with a portionbroken away showing part of the jar. Fig. 2 is a central verticalsectional view of the invention, showing the cover closed. Fig. 3 is afront elevation of the lock. Fig. a is an elevation of the hinge. Fig. 5is a sectional view of a portion of the jar and cover with the coverclosed.

Fig. 6 is a view of the same parts with the cover partially raised.

Latitude is allowed herein to details, as they may be changed or variedat will Without departing from the spirit of my invention and the sameremain intact and be protected.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

My invention consists of a jar-cover hinged to a metallic or othersuitable clamping or screwing device and adapted to be applied to thejar a, which may be of glass, porcelain, or other suitable material.-The jar e forms no part of the present invention; but my device isparticularly adapted to be attached to the glass jars a, .having theannular beads or ribs b, which are now in common use in stores forholding and displaying pickles, pickle-limes, &c. It is necessarythatthe top of the jar be made of considerable thickness; otherwise thecover could not be properly attached, and to this rib b is fastened themetallic rim or ring (Z, which is made of sufcient size and shape so asto slip upon the rib b, and it extends nearly around the upper side ofthis rib of the jar; but its two ends are not connected at the point r/in the rear portion of the jar except by the clamping screw or bolt L.

Upon the enlarged portion or rib is stretched a band of thin rubber orother suitable material c, which allows the metallic rim Z to betightened upon the jar without injury to the glass. The rubber c extendsabove the rim d, and the stretching process brings the protecting' partof the rubber fiat and extending inward toward the center of the jar.The weight of thecover when closed forces down the protecting edge ofthe rubber c, thus producing the desired suction. The rubber cloth orother material c extends partly beyond the rim d toward the center ofthe jar, forming a flat ledge or depending inwardly-inclined annularflange, as shown in the lower part of Fig. 6, and is so arranged as tosuck down or hold the cover or lid e against accidental displacement,the cover e being preferably vmade of indurated wood fiber or pressedpaper and concaved, having at its outer ed ge the up- IOO ward andoutward extending' rim d, so that when the cover is' dropped or let downupon the projecting' rubber band it presses it down, as shown in Fig. 5,to such a position that it forms an air-tight fitting, and a suction iscaused thereby, so that some slig'ht force is required to lift the covere from the rubber c, and for this purpose a handle p is attached to theupper portion of the cover, as shown in Figs. l and 2.

The cover e is preferably locked against the rim Z by a lock s, attachedto the eoncaved part of the cover e by a screw t and to the rim c by arivet q, and is provided with a hing'ed portion fr, having' the arms /r/for fastening or clamping to the under side of the metallic rim d, whichrim is preferably made of' aluminiuln.

rlhe rubber c extends entirely around the rib 7) of the jar,'so that ithas to be stretched around it, and if made of the proper size the innerportion will raise up, as shown in Fig. 6, when the cover of the jar israised from the jar itself. The rim Z does not extend entirely aroundthe jar; but a portion is cut away, as shown at (y, at the rear of thejar and diametrically opposite the hinge s, and in this space g isattached the hinges of the cover. As there is always a variation in thesize of glass vessels, it is necessary to have two hinges, and thisovercomes the variation, as the rim (Z has to be tightened and the coverput in its proper position before the bolt or rivet holes are bored inthe cover. I

The rim d has at each of its ends outwardextending projections or arms ff, through which are inserted a bolt t, which bolt has a screw-head 1and is provided with a nut j, and as it is screwed up upon the bolt /Lit tightens the rim d against the rubber c and upon the rib of the jara, as shown in Fig. 4. Upon this bolt are pivoted arms i e', whichextend upward and then at right angles inward and are attached to therim e of the cover e by the rivets m and to the cover e by the bolts m.The arms f are cut away, as shown in Fig. 2, forming seats o, againstwhich the shoulders f of the arms rest when the cover e is raised, thusholding the cover in an upright position and preventing it from fallingtoo far back.

Having' thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is-

l. A jar-cover consisting of an outwardlyconvexed metallic strip havingarms at each of its ends, tightening means connecting the arms, hingespivoted to the tightening' means,

and a cover attached to the hinges, substantially as shown anddescribed.

2. A. jar-cover comprising a cover, a rim, a rubber band held within therim and having an inwardly-extending upper edge, a bolt for tighteningthe rim upon the jar, a hinge pivoted to the bolt and having its leafsecured to the cover, all substantially as shown and described.

3. A jar-cover in combination with a jar having an enlarged rib, a rimextending nearly around the periphery of the jar and havingoutward-extending fianges at each end, a bolt connecting the flanges forsecuring' the rim against the rib, a cover, a hinge secured to the coverand pivoted on the bolt, and a strip of' elastic material insertedbetween the rim and rib and having a portion thereof extending withinthe jar, substantially as and for the purposes specified.

et. In a jar-cover in combination with ajar, a rubber band encirclingthe upper outer part of the jar, a metallic fastening encircling theband but having an opening in its rear portion, a hinge attached to eachend portion, adjusting' means connecting the hinges, a cover attached tothe leaf of the hinges, and locking means attached to the cover forlocking the cover against the rubber band, substantially as shown anddescribed.

5. A jar-cover consisting of a cover, a rim for securing the cover to ajar and having outwardly-extending flanges, each flange being' providedwith a seat, a bolt connecting' the flanges for tightening the rimagainst the jar, hinges pivoted on the bolt and having' shoulders forresting upon said seats and holding the cover in an uprig'ht positionwhen raised, substantially as shown and described.

6. In a jar-cover in combination with a jar having' an enlarged rib, ametallic strip extending nearly around the rib and having at each of'its ends outwardly-extending arms, each arm having' an enlarged part,means connecting the arms for tightening the strip against the rib, acover, hinges attached to the cover and pivoted on the tightening means,and the hinges arranged to come in contact with the enlarged part of'the arms on the backward movement of the cover substantially as and forthe purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRED l). PURDY.
